display udp status

Function

The display udp status command displays information about IPv4 UDP connections.

Format

display udp status [ local-ip ipv4-address | local-port local-port | remote-ip ipv4-address | remote-port remote-port ] ^* [ cid cid ] [ socket-id socket-id ]

Parameters

Parameter	Description	Value
local-ip ipv4-address	Displays the IPv4 UDP connection with a specified local IP address.	The address is a 4-digit decimal number, in the format of X.X.X.X.
local-port local-port	Displays the IPv4 UDP connection with a specified local port number.	The value ranges from 0 to 65535.
remote-ip ipv4-address	Displays the IPv4 UDP connection with a specified remote IP address.	The address is a 4-digit decimal number, in the format of X.X.X.X.
remote-port remote-port	Displays the IPv4 UDP connection with a specified remote port number.	The value ranges from 0 to 65535.
cid cid	Displays information about the IPv4 UDP connection with a specified APP CID.	The value is a hexadecimal integer ranging from 0 to ffffffff.
socket-id socket-id	Displays the IPv4 UDP connection with a specified socket ID.	The value is an integer that ranges from 0 to 2147418111.

Usage Guidelines

Usage Scenario

UDP is a communications protocol used for packet switching on the Internet. It uses the simplest transmission model to send messages from one user application to another. To monitor the UDP connection status, run the display udp status command to check the following information:

IPv4 UDP Socket ID
APP Cid
Local IPv4 address
Local port number
Remote IPv4 address
Remote port number
FeNode ID

Precautions

No information is displayed if there is no UDP connection on the device.

Example

The actual command output varies according to the device. The command output here is only an example.
